British Oz. Tall Boy US prototype designation T10, M109 series
British aerial anti-surface bomb against hardened targets. Its development was completed at the end of World War II to a design by Barnes N. Wallis.
The first use of the British 12,000-pound bomb occurred on the night of 8-9 June 1944, during a raid against the Saumur railway tunnel. Of the nineteen (Note: other figures speak of eight) bombs used, at least one hit the hill above the tunnel. The rock cave-in and collapsed ceiling for about 6,000 feet made traffic impossible for several weeks. The air raid made it impossible for the Germans to get enough of their troops into Normandy to fight the Allies.
TTD British version Overall length 21' / 6.4 m Body diameter 38" / 0.965 m Stable span ... Estimated impact speed up to 3700 ft per sec. / 1127.8 m per sec. Weight 12622 lb / 5725.2 kg Torpex D1 explosive used, 5200 lb / 2358.7 kg No. 58 Mk. I allowed to set several blast delay options, from 0 sec. to 11 sec. The No. 47 igniter allowed for several blast delay options in minutes, up to a maximum of 60 min. Production order placed on 18 July 1943 Production licence granted to the United States - 125 built here Total production 854 units
Note In converting British measurements to the SI system, account was taken of their difference from the North American system.
Some sources give the designation of the North American prototype T39 and the production model M123. It can be assumed that these figures belong to the "combat" part of the bomb.
